Description

A mirror ball marker {A mirror ball marker}

The present invention relates to a mirror ball marker, and more specifically, to a mirror ball marker, which has a mirror surface that corrects putting posture and movement and indicates the putting direction to the hole cup, has a laser pointer that determines the slope of the green near the hole cup, and has a golf ball marker. It relates to a mirror ball marker equipped with a level that determines the slope of a located point.

Generally, golf consists of a tee shot, fairway shot, and putting shot. In particular, the most important thing in golf scores is the putting shot. Putting is determined by direction and distance, and direction is especially important, so you must read the green well, set the putting line, aim accurately, and then make a perfect stroke.

Here, the elements of putting are ball speed, measurement of distance, and putting with sufficient force. In other words, aiming the direction accurately and putting with enough force to slightly pass the hole cup are important factors for successful putting.

In order to accurately aim the putting direction, you must imagine and hit the exact putting line (the line where the ball is expected to roll) with respect to the hole. At this time, the position of the golfer's eyes should be exactly aligned with the putting line to ensure that the putter's hitting surface is hit. Accurate putting is achieved only when the dot is aligned with the center of the ball at a right angle along the putting line.

However, golf beginners or general golfers may not be able to align their eyes with the putting line due to their head shaking or posture shaking when putting, making it impossible to send the golf ball in the desired putting direction.

In addition, the putting direction and putting strength must be adjusted according to the slope or curve of the green near the hole cup. The green near the hole cup is generally not flat and has slight slopes or curves on purpose, which makes putting difficult for ordinary golfers.

In general, golfers use a golf club to measure the slope or slope of the green, or sit down and measure the slope of the green to determine the slope or curve before putting.

However, the green and surrounding environment are almost green, there are obstruction factors such as trees planted at an intentional angle, and golfers have difficulty measuring the slope of the green due to an optical illusion, so they measure the slope incorrectly when putting and end up putting. There are many cases where you fail and lose the game.

However, when putting, a ball marker is placed at the point where the golf ball was located to indicate the position of the golf ball.

A typical ball marker is generally made in the shape of a flat plate like a coin and barely protrudes from the ground when placed on the green, so even if someone else's ball passes over it, it does not significantly affect the path of the ball.

However, the conventional ball marker simply has the function of indicating the position of the ball. It accurately indicates the position of the golfer's eyes when putting, corrects the putting address posture and putting stroke, informs the putting line or putting direction, or displays the hole cup. There is a need for a ball marker that indicates the slope of the green in the vicinity or near the golf ball.

Hereinafter, the present invention will be described in detail with reference to the drawings. The present invention may be subject to various changes and may have various forms, and should be understood to include all changes, equivalents, and substitutes included in the spirit and technical scope of the present invention.

Referring to Figure 1, the mirror ball marker 100 according to an embodiment of the present invention includes a mirror surface portion 10 in which the golfer's eyes are reflected and displayed; It is comprised of a main body 20 formed below the mirror surface portion 10, and a marker part 30 formed below the main body 20 to indicate the position of the golf ball.

As shown in FIGS. 1(a) and 1(b), the mirror ball marker 100 of the present invention has a curved concave portion 40 formed on the side in contact with the golf ball identical to the outer contour of the golf ball, forming a mirror ball marker. The marker 100 can be placed as close to the golf ball as possible without coming into contact with the golf ball.

Figure 1(a) illustrates the mirror surface portion 10 of the ball marker 100. The mirror surface portion 10 has aiming lines 11 to 13 that facilitate aligning the golfer's eyes or head with the hole cup. ) are formed.

The left aiming line 11, the center aiming line 12, and the right aiming line 13 of the mirror surface portion 10 are formed parallel to each other, the central aiming line 12 is formed to coincide with the center of the golf ball, and the left and right aiming lines 11 , 13) are formed to be spaced apart from the central aiming line 12 by approximately 1/4 to 1/3 of the golf ball diameter.

The present invention can be placed as close to the golf ball as possible due to the concave portion 40 of the ball marker 100, making it easy to align the center aiming line 12 of the mirror surface portion 10 with the center of the golf ball.

When using the ball marker 100 of the present invention for fitting address and putting-spot posture correction, the mirror surface portion 10 is positioned upward, and the center aiming line 12 is aligned with the center of the golf ball to create the ball marker 100. After positioning the concave portion 40 closely to the golf ball, when the golfer takes a putting posture, the golfer's head, especially the eyes, are displayed on the mirror surface portion 10.

At this time, the golfer can putt the golf ball to the desired putting line by aligning the golfer's eyes (E) to coincide with the central aiming line (12). Additionally, the golfer can use the mirror surface portion (10) to move the golfer's head during putting. can be easily grasped, and the putting posture can be corrected using the mirror surface portion 10 of the mirror ball marker 100.

The main body 20 of the mirror ball marker 100 of the present invention is manufactured to have a weight that does not blow away in strong winds. Materials such as iron, synthetic resin, and stainless steel can be used, but stainless steel, which is easy to mirror finish, is used. It is desirable to use

In addition, it is preferable that the mirror ball marker 100 is made of a magnetic material, and for this purpose, it is preferable to use stainless steel of the martensitic SUS410 or ferritic SUS430 series, which contains little nickel.

Alternatively, when using austenitic SUS304 containing nickel, strain-induced martensitic stainless steel is used in which the austenitic S304 is cold-rolled to destroy the austenite structure on the surface to make it magnetic. It is desirable to do so.

In addition, the mirror surface portion 10 of the ball marker 100 is No. 1, which has a dull gray glossy finish through a post-processing process such as hot rolling and annealing. 2B stainless steel, which is manufactured by cold rolling and polishing stainless steel again, can be manufactured by sequentially grinding #400, #600, and #800 and then chrome plating.

Alternatively, when the main body 10 of the ball marker 100 uses a material that is difficult to mirror-surface process, the mirror-surface portion 10 of the ball marker 100 is formed by attaching an aluminum plate or glass mirror with a reflective surface to the upper part of the main body. It can also be formed.

The marker portion 30 of the mirror ball marker 100 of the present invention is formed on the opposite side of the mirror surface portion 10, forming a light reflection pattern that facilitates confirmation of the position of the golf ball, and, if necessary, promotional phrases or designs. By attaching printed pattern paper, the ball marker can be used as a promotional tool for a company or business.

Additionally, if necessary, a permanent magnet can be embedded in the marker portion 30 to enable it to be attached and detached from other golf equipment.

Next, the ball marker 100 provided with the mirror surface portion protection jaw 15 of FIG. 2 will be described.

The mirror surface portion 10 of the ball marker 100 has a reflective surface to easily check the position of the golfer's head or eyes. When the putter contacts or passes by the mirror surface portion 10 during putting, the mirror surface portion ( If scratches or scratches occur on the reflective surface of the mirror surface portion 10 and this phenomenon occurs for a long period of time, the reflective surface of the mirror surface portion 10 may lose its reflective function.

In order to solve this problem, a protective protrusion 15 can be formed on the mirror surface portion 10 of the ball marker 100 itself, as shown in FIG. 2(a), and a mirror surface portion is formed on the circumferential edge of the mirror surface portion 10. A protective protrusion (15) is formed that protrudes by approximately 1 to 3 mm from (10).

Alternatively, as shown in FIG. 2(b), the ball marker 100 itself is closely embedded in a separate storage frame 110 and the circumferential edge of the storage frame 110 is protected by protruding about 1 to 3 mm beyond the mirror surface portion 10. Form the chin (15).

Next, an example of using the ball marker 100 to correct the putting posture will be described with reference to FIG. 3 .

First, the aiming mark (M) of the golf ball (B) is aligned with the virtual putting indicator line (P) pointing toward the hole cup (H).

Next, the mirror surface portion 10 of the ball marker 100 is positioned upward, and the center aiming line 12 is aligned with the aiming marker M of the golf ball B to form the concave portion 40 of the ball marker 100. ) is placed closely to the golf ball.

Next, the golfer assumes a putting posture and places his head, especially his eyes, on the mirror surface portion 10.

Next, the golfer's eyes (E) are aligned to match the central aiming line (12) of the mirror surface, and the golfer's eyes (E) are aligned to match the virtual putting indicator line (P).

Through the above process, the golfer can easily identify the golfer's head movement when putting using the mirror surface portion 10, and trains the golfer's eyes to match the central aiming line 12 even after the putting operation is completed. Putting posture can be corrected by suppressing head movement and mastering aligning the golfer's eyes with the desired virtual putting indicator line (P) when putting.

Figure 4 is a drawing of an actual work of a mirror ball marker according to an embodiment of the present invention. As shown in Figure 4, the mirror surface portion 10 of the mirror ball marker 100 clearly shows the golfer's eyes and nose. It has a reflective surface that can be seen.

In addition, the aiming lines 11 to 13 of the mirror surface portion 10 are formed clearly enough to align the positions of the golfer's eyes when the golfer's head is positioned.

The mirror ball marker 100 of the present invention can be used by attaching and detaching a level 120 that measures the slope of the point where the golf ball is located, as shown in FIG. 5, or by embedding the level 120 in the main body 20 of the ball marker 100. there is.

In the level 120 of the present invention, the vertical level 121 and the horizontal level 122 are arranged in a cross shape, the insides of each level 121 and 122 are filled with liquid and contain air bubbles 123, and the level 120 ) A permanent magnet 124 is embedded in the lower part to enable attachment and detachment from the mirror ball marker 100.

The golfer can use the level 120 by attaching it to the mirror ball marker 100 or use it alone, and determine the position of the air bubble 123 inside the vertical level 121 and the horizontal level 122 of the level 120. Through this, you can determine the front, rear, left and right inclinations of the point where the golf ball is located.

For example, when the horizontal level 122 of the level 120 is positioned to align with the virtual putting indicator line or the aiming mark (M) of the golf ball, the air bubble 123 is moved from the horizontal level 122 to the golf ball side. If it is biased, you can see that the green slopes upward from the golf ball position to the hole cup side, that is, in the front hole cup direction.

However, there is a problem that the level 120 alone cannot determine the green slope from the golf ball position to the hole cup or the overall green slope on the virtual putting instruction line (P).

The present invention additionally uses a green slope determination device 200 as shown in FIG. 6 to partially solve this problem.

The green slope determination device 200 of the present invention includes a level 120 that measures the green slope at the point where the golf ball is located and laser pointers 220 and 230 that measure the green slope near the hole cup.

The green slope determination device 200 includes a level 120 disposed at the upper center of the rectangular frame 210, a left laser pointer 220 disposed on the left and right sides of the level 120 spaced apart by the radius of the golf ball, and Right laser pointer 230; and a permanent magnet 250 embedded in the lower and/or upper part of the square frame 210 so as to be detachable from the mirror ball marker 100, level 120, or green speed detection device 400, which will be described later. 270).

In addition, the square frame 210 has a built-in battery for the laser pointers 220 and 230, and a switch 240 is installed on the upper surface. The switch 240 turns on each laser pointer 220 and 230 simultaneously or independently. /can be configured to turn off.

In addition, each laser pointer 220, 230 is installed on the square frame 210 by a rotation axis 222 so that it can be rotated in the range of -10 degrees to +10 degrees.

In addition, the left and right laser pointers 220 and 230 emit different colors, for example, the left laser light emits red and the right laser light emits blue, making it easy to distinguish between the left and right light beams.

The mirror ball marker 100 and the green slope determination device 200 of the present invention can be conveniently stored and used by being attached to a hat cap by a hat holder 300, as shown in FIG. 7.

The hat holder 300 includes a holder body 310, a permanent magnet 320 embedded therein, and an elastic clip 330 attached to one side of the holder body 310.

The hat holder 300 attaches the magnetic mirror ball marker 100 with magnetic force, and the green slope determination device 200 is attached to the mirror ball marker 100 by its own permanent magnet 250, thereby attaching the mirror ball marker 100 to the mirror ball marker 100. Both (100) and the green slope determination device (200) are directly or indirectly attached and stored to the hat holder (300) by magnetic force.

Next, referring to FIG. 8, it will be explained how to determine the slope of the green on the left and right sides of the hole cup using the green slope determination device 200 of the present invention.

First, the golfer uses the green slope determination device 200 to align the horizontal level 122 of the level 120 of the green slope determination device 200 so that it matches the virtual putting indicator line (P). Perform the sorting step.

Alternatively, when the ball marker 100 is magnetically attached to the green slope determination device 200 instead of the level 120, the center aiming line 12 of the mirror surface 10 of the ball marker 100 is the virtual putting indicator line (P ) performs the alignment step of the green slope determination device 200 to align it to match.

Next, a left and right laser pointer rotation step is performed in which the left and right laser pointers 220 and 230 of the green slope determination device 200 are rotated left and right to irradiate the left and right sides of the hole cup H.

At this time, the rotation angle of the left and right laser pointers (220, 230) becomes smaller as the target point for irradiating the laser light is further away from the left and right sides of the hole cup (H), and also, the closer the distance between the laser pointers (220, 230) and the hole cup (H) becomes. It gets bigger.

Next, a laser irradiation step is performed in which the left and right laser pointers (220, 230) are operated with a switch to irradiate the left and right sides of the hole cup (H) with laser.

Next, the golfer performs a reflected light confirmation step in which the laser light from the left and right laser pointers 220 and 230 collides with the green and visually checks the reflected light.

Next, when the reflected light is confirmed, the golfer performs a slope determination step in which it is determined that the green on the side where the reflected light exists (left or right of the hole cup) has an upward slope.

The closer the reflected light is to the laser pointer (220, 230) or the green slope determination device, the steeper the green slope to the hole cup is, and the farther the reflected light is from the laser pointer (220, 230) or the green slope determination device, the steeper the green to the hole cup is. The slope can be judged to be gentle.

Looking at the example of FIG. 8, it can be seen that the green slope of the left hill is gentler than the green slope of the right hill because the position of the left reflected light (A) is further from the green slope determination device than the position of the right reflected light (B).

If there is a hill or slope on one of the left and right sides of the hole cup, the golfer must perform a putting leader (P) correction step to move the virtual putting leader (P) to the side where reflected light exists (left or right of the hole cup) depending on the slope. .

However, in general, the putting indicator line (P) is corrected to the right or left of the hole cup (H) according to the slope of the green, such as 1/2 hole cup, 1 hole cup, 2 hole cup, etc., so in order to determine the degree of correction, the slope of the green It is necessary to roughly understand the extent.

Next, using FIG. 9 as an example, it will be explained how to determine the green slope on one side of the hole cup.

First, the left and right laser pointers 220 and 230 of the green slope determination device are aimed at one side of the hole cup judged to have a hill or slope, but are rotated parallel to each other, and then a laser pointer alignment and aiming step is performed to emit laser light.

Figure 9 shows a state in which it is determined that there is a hill to the left of the hole cup (H), and the left and right laser pointers 220 and 230 are aligned to face the left side of the hole cup (H) and laser light is emitted.

Next, the golfer checks the location of the reflected lights (A1, A2) reflected from the hill or slope on one side of the hole cup and determines the distance (L1, L2) of the reflected lights (A1, A2) and the reflected lights (A1) from the green slope determination device. , A2), perform a slope determination step to determine the slope of the hill or slope by determining the distance (d) between them.

Figure 9 shows that among the reflected lights (A1, A2) reflected from a hill or slope on one side of the hole cup, the distance (L1) between the reflected light (A1) and the green slope determination device is the distance (L2) between the reflected light (A2) and the green slope determination device. It can be determined that the green slope at the point of reflected light (A1) is greater than the green slope at the point of reflected light (A2).

Additionally, it can be determined that the farther the distance (d) between the reflected lights (A1, A2) is, the gentler the drawn slope is, and the closer the distance (d) between the reflected lights (A1, A2) is, the greater the drawn slope is.

Next, the golfer performs the slope determination step and adjusts the distance between the virtual putting indicator line (P) to the right or left of the hole cup (H) according to the slope of the green identified to determine the virtual putting indicator line (P). Perform correction.

In addition, the present invention can increase the rotational freedom of the left and right laser pointers 220 and 230 of the green slope determination device in order to more precisely determine the green slope on the left and right before and after the hole cup (H).

To this end, in the present invention, as shown in FIG. 10, the left and right laser pointers 220 and 230 are installed on the installation frame 210 by a ball joint 260 and can rotate up, down, left and right.

Next, Fig. 11 explains how to determine the green slope before and after the hole cup using laser pointers 220 and 230 that can rotate up, down, left, and right.

In Figure 11, the inclination of the front of the hole cup (H) is measured by irradiating laser light while rotating the laser pointers (220, 230) up and down at certain angles. The larger the gap between the reflected lights (R1, R2, R3) reflected by the laser beams of the laser pointers (220, 230) hitting the green slope, the gentler the green slope is, and the smaller the gap between the reflected lights (R1, R2, R3) is. It can be judged that the green slope is steep.

The putting strength can be adjusted according to the slope of the green in front of the hole cup (H) identified in this way, thereby improving the putting success rate.

Here, rotating the laser pointers 220 and 230 up and down at certain angles can be done manually or with a separate controller by installing a separate step motor for up and down movement instead of a ball joint.

In addition, the laser pointers 220 and 230 can be used simultaneously or independently to determine the green slope in front of the hole cup (H).

In addition, the left and right rotations of the laser pointers 220 and 230 are performed simultaneously to determine the green slopes in front and on the left and right sides of the hole cup (H), thereby expanding the slope measurement range and improving the measurement speed.

In addition, since the putting strength must be adjusted according to the green speed when putting, the present invention provides a green speed detection device 400 that measures green speed as shown in FIG. 12, and the green speed detection device 400 is a green slope determination device. It can be used attached to (200) or used independently from the green speed detection device (400).

The green speed detection device 400 of the present invention can be magnetically attached to the green slope determination device 200, and includes a sensor unit 410, a weight 420 located on the upper part of the sensor unit, and a weight 420. ) It is configured to include a control unit 430 and a display unit 440 located at the top.

The weight 420 of the green speed detection device 400 has sufficient weight to determine the hardness of the green grass, and the sensor unit 410 includes a sensing rod 411 and an elastic support for measuring the hardness of the green grass. It includes a piece 412, and the control unit 430 determines the hardness of the green grass according to the measured value of the sensor unit 410.

At this time, the control unit 430 stores the firmness of the green grass, that is, green speed information according to the sensor measurement value, in a lookup table in advance, and outputs the green speed information according to the sensor measurement value of the sensor unit 410.

Additionally, the display unit 440 displays the green speed information output from the control unit 430 in text, color, or sound.

The green speed detection device 400 may have a battery built into the control unit 430 as a power source, and the weight of the weight 420 is at least 10 times greater than that of the green slope determination device 200, making it a green speed detection device. Even if 400 is attached and used together with the green slope determination device 200, it is desirable to minimize the influence due to the weight of the green slope determination device 200.

Figure 13 is a diagram explaining the configuration of the sensor unit 410 of the green speed detection device 400. The sensor unit 410 includes a detection rod 411 inserted into the green to measure the hardness of the green grass, and a detection rod ( It includes a plurality of elastic support pieces 412 that elastically support 411).

Figure 14 explains a method of measuring green hardness using the sensor unit 410 of the green speed detection device 400.

First, when the green speed detection device 400 is placed on the green grass so that the sensing rod 411 is in contact with the green, the sensing rod 411 of the sensor unit 410 is inserted into the green grass by the weight of the weight 420. do.

At this time, if the green grass is hard, it is difficult for the sensing rod 411 to be inserted through the green as shown in Figure 14(a), so the resistance is large, so the amount of insertion of the sensing rod 411 into the green is small, and instead, the sensing rod (411) is inserted into the green. The amount of deformation of the elastic support piece 412 that elastically supports 411 increases.

On the other hand, if the green grass is soft, the detection rod 411 is easy to insert through the green as shown in FIG. 14(b), and the resistance is small, so the amount of insertion of the detection rod 411 into the green increases, and instead, the detection rod (411) is inserted into the green. The amount of deformation of the elastic support piece 412 that elastically supports 411) becomes small.

The sensor unit 410 of the green speed detection device 400 measures the amount of deformation or deformation stress of the elastic support piece 412 and outputs the measured value to the control unit 430, and the control unit 430 controls the green speed detection device 400. ) The green speed corresponding to the measured value is output to the display unit 440 using a look-up table in which the amount of deformation, deformation stress, and green speed according to the weight of the green and the hardness of the green are stored in advance.
